In this paper we analyse the meaning planned by a teacher to introduce the Central Limit Theorem to engineers. This meaning takes into account the nature of variables and different approaches to the distribution of the sum or random variables. The planning of teaching is based on the mathematical knowledge about the theorem and the theoretical framework about semiotic functions, which is curren...

Normally, academic applications of computer-aided design in construction provide a visual presentation of the final state of the project and they are not able to produce changes in the geometry following the construction process. It was developed a didactic prototype that allows physical changes in a building component. This prototype illustrates the construction of common external wall. First,...

The key contribution of computer science to general and school education relies on the concept of Computational Thinking. Teaching programming in Logo at the primary school is an appropriate didactic approach towards Computational Thinking, it permits to embed Computational Thinking into a spiral curriculum at a very early stage and should enable specific transfer to related school subjects. Th...

The paper presents selected problems concerning the development of mobile applications for Android on example calculator program. author demonstrated possibilities didactic application this type projects.

The study presented here concerns the results obtained from the development and the experimentation of a didactic exergame realized by the University of Salerno. The aim of this exergame, called “Gioco delle Forme”, is to evaluate, measure and “train”, by means of a playful activity with a high degree of body involvement, the skills of visual and motor integration, skills that for scientific li...

I critically examine some recent work on the philosophy of scientific fictions, focusing on the work of Winsberg. By considering two case studies in fracture mechanics, the strip yield model and the imaginary crack method, I argue that his reliance upon the social norms associated with an element of a model forces him to remain silent whenever those norms fail to clearly match the characteristi...

Case study method of didactic situations is a modern procedure of effective development of professional abilities in future teachers. I have been using the method for many years in future teachers training in the field of preparation of subject methodologies. A case study does not develop only the subject and didactic competences of future teachers. The self-evaluation and self-reflection proce...

Considering that access to information is one of the most important aspects of modern society, the actions of certain governments or internet providers to control or, even worse, deny access for their citizens/users to selected data sources has lead to the implementation of new communication protocols. TOR is such a protocol, in which the path between the original source and destination is rand...
